This invention relates to sign support. constructions embodying new and useful improvements in the assembly and installation of sign supports of tubular construction.

rlhe assembly and installation of tubular elements to form a sign support forming the principle of this invention has for its object the elimination of various ttings, such as unions or attachments heretofore required in obtaining a complete connection between angularly disposed tubular members.

lith the above and other objects in view, as will be apparent, this invention consists in the construction, combination and arrangement of parts all as hereinafter more fullyV described, claimed and illustrated in the accompanying drawings, wherein:

Fig. 1 is a fragmentary view illustrating in full lines a single sign with cross arm enibodying the means -of connection forming the object of this invention, the portion in dotted lines indicating the complete assembly of parts when a double sign is desired;

Fig. 2 is an enlarged fragmentary cross sectional view taken along line 2-2 ofF ig. 1;

Fig. 3 is an enlarged fragmentary cross sectional view taken along line 3-3 of Fig. 1; and

Fig. 4 is an enlarged fragmentary cross sectional view similar to that of Fig. 3 and illust-rating in particular means for substituting a. double sign for a single sign.

Reference being had more particularly to the drawings 10 designates an upright or vertical tubular member forming the main or base portion of the sign support contemplated herein. rlhis upright 10 may be suitably anchored in the ground.

A pair of aligned apertures 11 are formed in the upper end of the upright 10 and coact to receive and retain the cross arm 12 extending therethrough and on opposed sides of said upright 10. The intersection of the support 10 and cross arm 12 is held in fixed position by means of a bolt 13 arranged to pass through the walls of the upright 10 transversely to and completely through the section of the cross arm confined therein as shown in Figs. 2, 3` and 4.

The rigidity of the intersection or attachment of the yupright 10 :and cross armVr 12 is further obtained by means of a cap or closure 16 adapted to be screwed on the threaded portion of the cross arm 12 and to fit tightly i against the outer surface of the upright 10 L!- at'the portions surrounding the aperture as shown 1n Fig. 3.

1n order that electric light wires may be conveniently delivered from the upright 1() to the cross arm 12 a wire receiving aperture 19 is drilled in that portion of the cross arm confined within the upright 10. By removing the cap 16 complete access to the wiring of the'upright member 10, as well as the cross arm -12 is made possible.

As will be noted from Fig. 1, the cross arm 12 furnishes a means for holding a display bearing member 17 by means of suitable attachments 18.

While the aforesaid description contemplates a sign. support of a single cross arm type as distinguished from a doublecross arm assemblyit will, of course, be noted that by substituting for the cap 16 a coupling or union 21, as shown in Fig. f1, an extension 22 may be fitted to the cross arm 12.

The exposed openings on the cross arm 12 port and that a sign supportof greater rigidity and strength is provided. By means of the removable cap at the end of the cross arm access may be had to the interior of the upright and the cross arm whereby electrical connectionsmay be drawn up through the upright, passed through the opening in the Y,

cross arm and delivered to the interior of the cross arm, after which the cap may be replaced.

What is claimed is:

1'. `The combinationwith a tubular upright .s

having a pair of aligned apertures therein,

of a cross arm snugly fitted in said apertures, one end of said cross arm adjoining said upright being threaded and a cap secured to said threaded end, a bolt passing through said upright and through the portion of the cross arm within the limits ofthe upright.

2. The combination with a tubular upright having a pair olf-retaining apertures therein, of a cross arm snugly fitted in said apertures, an opening in said cross arm Within the limits of said upright, and a portion of said cross arm adjoining said upright l being threaded, a bolt passing through said upright and through the portion of the cross arm confined Within the upright, and a Cap threaded on the threaded portion of the vcross arm.
